ABSTRACT:
A permanent magnet rotor for a brushless electric motor, comprising at least two main magnetic poles, disposed on a periphery of a rotor. Each opening angle A covers N/2 times the opening angle of each of the stator sections, with N being an odd number greater or equal to 3. A is required to be the nearest angle that is smaller than 360/P degrees, with P being the number of poles. Each of the main magnetic poles has a periphery with a central section R1and two end sections R2R1has an opening angle A1. The opening angle A1covers N/2 times the opening angle of each of the stator sections, with N being an odd number greater or equal to 3. A1is required to be smaller than the opening angle A of each of the main magnetic poles of the rotor. Each of the main magnetic poles contains a dual-plate permanent magnet.
